Natural Pebble Design: Crafted from resin with lifelike colouration, faithfully replicating riverbed pebble forms. Seamlessly integrates into aquariums, providing functional shelter while enhancing overall aquatic aesthetics. Hollow Structure: Internal cavity creates spacious, concealed areas for small ornamental fish and shrimp to hide, moult, or rest. Fixed Magnetic Attachment: Equipped with high-strength magnets, the shelter adheres firmly to either side of the aquarium glass. This allows observation of fish and shrimp activity inside without dislodging the shelter, even in strong currents. Versatile : Suitable for freshwater or saltwater aquariums, including shrimp tanks, small fish tanks, and ecologically landscaped tanks. We’re Here for You：Thank you for your trust.
